Methods of detection of swipe gestures and filtering and locating desired information in a multi-attributed search space in response to detection of swipe gestures and devices for performing the same are provided. The method includes activating an attribute associated with at least one element of a list of elements having a visible list portion rendered on the viewing area, in response to receiving an activation input for the attribute and displaying a plurality of attribute field controls associated with the attribute, in response to its activation. The method further includes receiving a manipulation action of at least one attribute field control, updating an attribute value in response to the manipulation action, and updating the visible list portion based on the attribute value. The method may be used with touchscreen displays, and with virtual or augmented reality displays.

FIELD

This disclosure relates generally to displaying lists of elements ondisplays of electronic devices and scrolling therethrough. Morespecifically, the disclosure relates to methods of detection of swipegestures and filtering and locating desired information in amulti-attributed search space in response to detection of swipegestures, and devices for performing the same.

BACKGROUND

Electronic devices often have touchscreen displays for displayingcontent in a viewing area thereof and for enabling user interaction withthe electronic device. Content displayed on a touchscreen display may bein the form of a long list of elements which does not fit entirely inthe viewing area of the touchscreen display. Scrolling is the action ofmoving displayed content (e.g. elements of a long list), such as text orgraphics, up, down, or across a viewing area in order to view differentelements of the long list. Scrolling is useful for locating desiredelement (e.g. text or graphics) in the long list of elements byscrolling at a faster rate.

Scrolling on traditional computer screens has relied mainly onscrollbars. A scrollbar is a user interface control element by whichcontent, such as continuous text, images, or graphics can be scrolled ina predetermined direction, such us up, down, left or right. The contentis scrolled so that all of the content can be viewed even if only aportion of the content fits in the viewing area of a display. Atraditional scrollbar includes a track and a draggable scrollingelement, such as a thumb, which can be dragged along the track to movethe content, such as body of a document or elements of a list ofelements, through a viewing area of a display. Dragging the draggablescrolling element along the track when the scrollbar is displayed on atouchscreen display is typically done by a user touching the draggablescrolling element with a finger to select the draggable scrollingelement and then dragging their finger along the track which causes thedraggable scrolling element to move along the track. Typically ascrollbar is located along one edge of the viewing area of the displayso the draggable does not interfere with displayed content.

Scrollbars with draggable scrolling elements have limitations whenscrolling through a long list of elements. When the scrolling element isat a top position on the track, this corresponds to the first element ofthe list of elements to be displayed. Similarly, when the scrollingelement is at a bottom position on the track, this corresponds to thelast element of the list of elements to be displayed. Screen size andresolution pose problems when the range between the first and lastelements is large. For example, if the number of elements beingdisplayed is at least an order of magnitude of the screen resolution,continuous scrolling which allows the viewing or selection of a singleelement becomes impossible as scrolling by even one pixel representsscrolling through ten or more elements. The OrthoZoom Scroller proposedby Appert and Fekete teaches swiping the scrolling element in adirection which is orthogonal to the axis of the track of a scrollbar inorder to zoom in and permit continuous scrolling of a list of elements.In use, the scrolling element is dragged along the track to pan along alist of elements. Then the scrolling element is dragged away from thetrack in an orthogonal direction to zoom in and change the scrollingscale to a finer granularity. The scrolling element may then be draggedin a direction parallel to the track to continuously scroll using thefiner granularity along a subset of the range so that a particularsingle element may be viewed or selected. However, Orthozoom Scrolleronly scales the scrolling but does not deal with elements havingmultiple attributes. Looking for a particular element in the list ofelements still involves panning and scrolling through every element inthe list.

Some applications display data, whether textual or graphical in the formof a long list of elements, wherein each element is multi-attributed innature. For example an application such as Google Photos displays a listof photos typically sorted by the date attributes of the photos. TheGoogle Photos application provides a traditional touch flick method ofscrolling in which a human finger or touch input tool is flicked eitherupwardly or downwardly on the screen to cause the content of theapplication's viewing area to scroll through the photos or videos beingdisplayed. The Google Photos application also provides a scrubber userinterface element as an alternate method of scrolling through content.The scrubber interface is described in more detail below. Scrollingthrough the photos using the scrubber is faster than traditional touchflicks as it allows skipping by a month at a time. However, the scrubberonly allows scrolling using the time attribute of the photos, and doesnot take into account other attributes associated with the photos suchas content and location.

There is a need for a more versatile way of scrolling through andlocating elements in a long list of elements displayed on touchscreendisplays.

SUMMARY

In some of the aspects of the present disclosure, the ability to scrollin a hierarchical manner and based on different attributes of theelements of a long list may improve the operation of an electronicdevice. For example, facilitating more efficient user interactions withan electronic device through the hierarchical scrolling may enablelocating an element with fewer, and more accurate interactions. Fewerinteractions with the electronic device reduce possible wear or damageto the electronic device and possibly reduce battery power consumption.

In one aspect of the present disclosure, there is provided a methodperformed by an electronic device having a display including a viewingarea. The method comprises activating a first attribute associated withat least one element of a list of elements having a visible list portionrendered on the viewing area, in response to receiving a firstactivation input for the first attribute; displaying a first pluralityof attribute field controls associated with the first attribute, on theviewing area, in response to activating the first attribute; andreceiving a first manipulation action of at least one attribute fieldcontrol of the first plurality of attribute field controls. The methodfurther comprises updating a first attribute value in response to thefirst manipulation action, and updating the visible list portion basedon the first attribute value.

In one aspect of the present disclosure, the preceding method mayfurther comprise activating a second attribute associated with at leastone element of the list of elements in response to receiving a secondactivation input for the second attribute; displaying a second pluralityof attribute field controls associated with the second attribute, on theviewing area, in response to activating the second attribute; receivinga second manipulation action of at least one attribute field control ofthe second plurality of attribute field controls; updating a secondattribute value in response to the second manipulation action; andupdating the visible list portion based on the first attribute value andthe second attribute value. Advantageously, a visible list portion of alist may be updated based on two attribute values which can lead todisplaying a desired number of elements with minimal scrolling or inputof filtering conditions.

In one aspect of the present disclosure, in the preceding method, thefirst attribute may be an ordinal attribute, updating the firstattribute value may comprise incrementing or decrementing the firstattribute value, and updating the visible list portion may comprisescrolling the viewing area until the visible list portion containselements matching the first attribute value. Scrolling the viewing areabased on a first attribute value which can be updated through amanipulation action of an attribute field control may minimize the needfor multiple touch flicks or other scrolling actions that would need tobe applied repeatedly until the visible list portion contains thedesired elements.

In one aspect of the present disclosure, in the preceding method, thedisplay may be a touchscreen display and the first manipulation actionmay comprise upwardly or downwardly in relation to the attribute fieldcontrol.

In one aspect of the present disclosure, in the preceding method, thefirst attribute may be a nominal attribute, the first plurality of fieldcontrols each contains a possible value for the first attribute,updating the first attribute value may comprise setting the firstattribute value to the possible value of the attribute field controlreceiving the manipulation action, and updating the visible list portionmay comprise displaying only elements of the visible list portion whichhave the first attribute value. Advantageously, a list of elements maybe filtered based on one or more attributes without the need to entercomplex Boolean conditions. This simplifies the user interface and maylead to less use of input peripherals and less use of the processingpower of the processing device.

In one aspect of the present disclosure, in the preceding method, thefirst manipulation action may comprise swiping to an attribute fieldcontrol then lifting off therefrom. The action is simple and intuitive.

In one aspect of the present disclosure, in the preceding method, thedisplay may comprise a touchscreen display. The viewing area may have ascrubber and an around scrubber area (ASA) rendered thereon near a oneedge of the touchscreen display. The viewing area may have an attributeselection view, comprised of a plurality of attribute selectionelements, rendered along an opposite edge of the touchscreen display.The first activation input may comprise a swipe from the around scrubberarea towards an attribute selection element. Advantageously, a singleswipe may be used to both activate an attribute and manipulate attributefield controls to update the selected attribute's value. The firstattribute may be activated when the swipe reaches a selection distancethreshold line. In addition to being a simple gesture, not touch flicksor repeated swiping actions are necessary. This reduces wear on thetouchscreen display which would otherwise have to undergo repeatedpressure when receiving touch flicks for example.

In one aspect of the present disclosure, in the preceding method, thedisplay may comprise a touchscreen display, the viewing area may have anattribute activation view, comprised of a plurality of attributeactivation elements, rendered along an edge of the touchscreen display,and the first activation input comprises touching an attributeactivation element corresponding to the first attribute then swipingaway from attribute activation view. Advantageously, selecting anattribute to activate is simplified and swiping away is a distinctgesture that will not be confused with a vertical swipe. This reducesthe chance of an accidental scrolling before selecting the attributevalue which would require additional interactions to cancel theaccidental scrolling. Unnecessary interactions with the touchscreendisplay are therefore minimized thus reducing wear on the touch sensingmechanisms and reducing battery power consumption.

In one aspect of the present disclosure, in the preceding method, theattribute view may be semi-oval and is rendered in response to touchinga scrubber, which advantageously does not permanently take up much spacein the viewing area. This averts the need to make the touchscreendisplay larger to view the same content, thus reducing cost.Additionally, a larger touchscreen display consumes more battery power,hence efficiently using the viewing area results in battery powersaving.

In one aspect of the present disclosure, in the preceding method, thedisplay may comprise a touchscreen display and the viewing area may havean attribute activation view comprised of a plurality of attributeactivation elements, rendered along an edge of the touchscreen display,and scrollable in the vertical direction in response to touch flicks.The viewing area may have a scrubber rendered thereon, the scrubberbeing aligned with one the plurality of attribute activation elements.The first activation input may comprise applying at least one touchflick to the attribute activation view until an attribute activationelement associated with the first attribute is aligned with thescrubber, and touching the scrubber.

In one aspect of the present disclosure, in the preceding method, thedisplay may be an augmented reality display, and a scrubber may berendered on the viewing area. The first activation input may comprise apinch and grab air gesture of the scrubber to expand the scrubber intoan attribute activation view comprising a plurality of attributeactivation elements, and swiping in mid-air towards an attributeactivation element of the plurality of attribute activation elements.Using a pinch and grab air gesture is intuitive for interacting with anaugmented reality display, and showing the attribute activation viewonly when needed saves viewing area real-estate and may reduce the needto make the display larger thus saving cost and power consumption.

In the preceding electronic device, the firstattribute may be an ordinal attribute. The instructions may furtherconfigure the processing device to update the first attribute valuecomprises incrementing or decrementing the first attribute value andupdate the visible list portion comprises scrolling the viewing areauntil the visible list portion contains elements matching the firstattribute value.

In one aspect of the present disclosure, in the preceding electronicdevice, the first attribute may be a nominal attribute, and the firstplurality of field controls may each contain a possible value for thefirst attribute. The instructions may further configure the processingdevice to update the first attribute value comprises setting the firstattribute value to the possible value of the attribute field controlreceiving the manipulation action, and update the visible list portioncomprises displaying only elements of the visible list portion whichhave the first attribute value.

In one aspect of the present disclosure, in the preceding electronicdevice, the instructions may further configure the processing device toactivate a second a second attribute associated with at least oneelement of the list of elements in response to receiving a secondactivation input for the second attribute, display a second plurality ofattribute field controls associated with the second attribute, on theviewing area, in response to activating the second attribute, receive asecond manipulation action of at least one attribute field control ofthe second plurality of attribute field controls, update a secondattribute value in response to the second manipulation action, andupdate the visible list portion based on the first attribute value andthe second attribute value.

In one aspect of the present disclosure, in the preceding electronicdevice, the display may comprise a touchscreen display and the viewingarea may have a scrubber and an around scrubber area (ASA) renderedthereon near a one edge of the touchscreen display. The viewing area mayhave an attribute selection view, comprised of a plurality of attributeselection elements, rendered along an opposite edge of the touchscreendisplay, and the first activation input may comprise a swipe from thearound scrubber area towards an attribute selection element.

In this disclosure, the term “touchscreen display” refers to acombination of a display together with a touch sensing system that iscapable of acting as an input device by receiving touch input.Non-limiting examples of touchscreen displays are: capacitivetouchscreens, resistive touchscreens, Infrared touchscreens and surfaceacoustic wave touchscreens.

In this disclosure, the term “touch input tool” refers to a physicaldevice, such as a stylus, used to create or manipulate content displayedon a touchscreen display.

In this disclosure, the term “scrolling gesture” refers to touching anddragging an element displayed on a touchscreen display in a direction toeffect scrolling the contents of a viewing area of the touchscreendisplay.

In this disclosure, the term “touch flick” refers to a gesture in whichthe screen of a touchscreen display is touched by a human finger or atouch input tool, the finger or touch input tool is briefly swiped inone direction and is then quickly lifted off the screen.

In this disclosure, the term “viewing area” or “view” refers to a regionof a display, which may for example be rectangular in shape, which isused to display information and receive touch input.

In this disclosure, the term “viewing area” or “main view” refers to thesingle viewing area that covers all or substantially all (e.g., greaterthan 95%) of the viewable area of an entire display area of atouchscreen display.

As discussed above in the background section, a list of elements whethergraphical or textual, may need to be displayed on a display of anelectronic device. FIG. 1A depicts an example list 200 of elements 210to be viewed on a viewing area 102 of a touchscreen display 45 of anelectronic device 10. The depicted list 200 is comprised of (N) elementsnumbered 210_1 through 210_(N) (collectively “210”). In one example,each element 210 of the list of 200 can be an image, a video, agraphical element or text. In another example, each element 210 can be agroup of sub-elements 212. For example an element 210 can be a group ofphotos taken on a particular date. The viewing area 102 of thetouchscreen display 45 can only show a visible list portion 216 of theelements 210 due to size limitations. For example, in the depictedexample, only the 3 elements: 210_(i−1), 210_i, and 210_(i+1) can bedisplayed in the viewing area 102. Element 210_i can be displayedentirely in the viewing area 102, while only portions of the elements210_(i−1) and 210_(i+1) are displayed in the viewing area 102.Accordingly, to view any of the other elements 210, such as element210_2, which is located within the list 200 and which is above thevisible list portion 216, the viewing area 102 of the touchscreendisplay 45 needs to scroll up the list 200 in the scrolling up direction19A. Similarly, to view any of the elements 210 which are below thevisible list portion 216, the viewing area 102 of the touchscreendisplay 45 needs to scroll down the list 200 in the scrolling downdirection 19B. Conventional methods of scrolling include touch flicks.To scroll the contents of the viewing area 102 of the display usingtouch flicks the screen of the touchscreen display 45 is touched by afinger, the finger is swiped either in the scrolling up direction 19A orin the scrolling down direction 19B, then the finger is lifted off thescreen. Other methods of scrolling are described below.

One of the other methods of scrolling through a list 200 of elements 210utilizes a user interface element known as a scrubber 18. FIG. 1Bdepicts an electronic device 10 including a touchscreen display 45having a viewing area 102. A scrubber 18 is rendered near a right edge45A of the touchscreen display 45 on the viewing area 102. The scrubber18 shown is generally circular or oval in shape and is sized to receivethe tip of a finger 30 or a touch input tool. The scrubber 18 can bedragged, by a finger 30 or a touch input tool, along a line 19 that issubstantially parallel to the right edge 45A of the touchscreen display45. For example, the scrubber 18 can be dragged in a scrolling updirection 19A to scroll up the contents rendered on the viewing area 102of the touchscreen display 45. Dragging the scrubber 18 in the scrollingup direction 19A is termed an “upward scrolling gesture”. Similarly, thescrubber 18 can be dragged downwardly in the scrolling down direction19B, in a “downward scrolling gesture”, to scroll down the contentrendered on the viewing area 102 of the touchscreen display 45.

In some example embodiments, the contents rendered on the viewing area102 are updated in real-time as the scrubber 18 is being dragged up ordown. In other embodiments, the content rendered on the viewing arearemains unchanged until the scrubber 18 is released by lifting thefinger 30 or the touch input tool off the screen when the finger 30 ortouch input tool is positioned on top of the scrubber 18.

In some embodiments, the position of the scrubber 18 indicates therelative position of the visible list portion 216 with respect to thelist 200 being displayed. For example, when the scrubber 18 is at atop-most position, shown as scrubber 18C, near the top edge 45C of thetouchscreen display 45, the viewing area 102 displays the elements 210at the top of the list 200. Conversely, when the scrubber 18 is at abottom-most position, shown as scrubber 18D, near the bottom edge 45D ofthe touchscreen display 45, the viewing area 102 displays the elements210 at the bottom of the list 200.

In some example embodiments, the scrubber 18 is not visible by defaultand is displayed in response to user interaction with the screen of thetouchscreen display 45. In one example, the scrubber 18 is displayed inresponse to a scrolling gesture by a hand or a touch input tool. Inanother example, the scrubber 18 is displayed in response to touchflicking the screen of the touchscreen display 45, by a finger 30 or atouch input tool. In other embodiments, the scrubber 18 is alwaysdisplayed to indicate the relative position of the currently displayedcontent in relation to the entire content or list of elements beingscrolled through, as discussed above. If the contents of the viewingarea 102 are scrolled using traditional touch flicks, the position ofthe scrubber 18 is updated to indicate the new relative position of thecurrent screen contents in relation to the entire content. In someexample embodiments, the scrubber 18 has a timeout associated therewith.Accordingly, when the finger 30 or touch input tool is released from thescrubber 18, the scrubber 18 is displayed for a few seconds then removedso it does not obscure any content of the user interface 14 of theapplication located under it

As an example of the use of the scrubber 18 to scroll through a list ofelements, FIGS. 2-4 depict an electronic device 10 having a touchscreendisplay 45 the viewing area 102 of which displays the user interface 14of a photo viewing application such as Google Photos™. The photo viewingapplication contains or has access to a list 200 of elements 210 whichcannot entirely fit on the viewing area 102 of the touchscreen display45. The user interface 14 includes a visible list portion 216 of a list200 of elements 210. The visible list portion 216 includes a pluralityof elements 210 each including one or more sub-elements 212. Theelements 210 each represents a group of photos or videos captured on agiven date. The sub-elements 212 are in the form of images 16. Eachimage 16 represents either a digital photo or a video. An image 16 canbe actuated to cause the photo viewing application to render thecorresponding photo or playback the corresponding video on at least partof the user interface 14.

The visible list portion 216 in FIG. 2 includes an element 210_i and anelement 210_i+1. The element 210_i includes a plurality of sub-elements212 including sub-elements 212_i and 212_i+1. The sub-elements 212 ofelement 210_i are in the form of images 16 representing photos and videotaken on a first date. The element 210_i+1 includes sub-element 212_1 inthe form of image 16 representing a photo or a video taken on a seconddate, which in this case is Thursday Aug. 19, 2010 as represented by thedate indicator 20.

The photo viewing application can be configured to sort the list 200such that the most recent elements 210 (and their sub-elements 212) areat the top of the list 200, or such that the most recent elements 210(and their sub-elements 212) are at the bottom of the list 200. In thedepicted example, the photo viewing application has been configured sothat the most recent elements 210 are at the top of the list 200. Eachgroup of images 16 captured on a particular date are rendered below adate indicator 20. For example, the image 16_1 corresponding tosub-element 212_1 is displayed below the date indicator 20 indicatingthat the corresponding photo or video was taken on Thursday Aug. 19,2010. Since the list 200 is sorted such that the most recent elements210 are at the top, then the images 16 corresponding to the sub-elements212 of the element 210_i, which are rendered above the date indicator20, were captured after the date indicated by the date indicator 20,i.e. after Thursday Aug. 19, 2010.

In some example embodiments, the contents of the viewing area 102 can bescrolled up or down by touch flick action as described above. Scrollingthrough a list of elements by touch flicks entails going through thelist 200 element by element. For a list 200, which is long, getting to aparticular element 210 which is far up or down the list 200 or in themiddle requires many touch flicks. As such, locating a particularelement using the touch flick scrolling method is both arduous and timeconsuming. For example, the constant touch flicking on the screenrequires processing every touch flick by a touch sensing system 112, atouchscreen driver 114 and a UI module 116 as will be described below.This processing consumes power and processing cycles thus potentiallydraining the battery. The touch sensing hardware may degrade from theconstant flicking. Furthermore, some users may experience carpal tunnelsyndrome (CTS) from repeatedly flicking their finger against the screenof the touchscreen display 45. Locating an element 210 of a list 200 insuch a time consuming manner also requires the touchscreen display 45 toremain on for a longer duration which consumes battery power.

One approach to address the limitations of scrolling by touch flicks isthrough the use of a scrubber 18, which was described with reference toFIG. 1B. With reference to FIG. 2, a scrubber 18 is displayed on theright side of the user interface 14 of the photo viewing applicationadjacent the right edge 45A of the touchscreen display 45. The scrubber18 provides improved functionality over the simple touch flick methoddescribed above. The scrubber 18 may be touched then either dragged downin a downward scrolling gesture or dragged up in an upward scrollinggesture. In response to dragging the scrubber 18, a plurality of yearfield indicators 22 each representing a year are displayed, as shown inFIG. 3. In FIG. 3, the scrubber 18 is not visible as it is hidden underthe user's finger 30. In response to dragging the scrubber 18, a monthfield indicator 24 and a plurality of year field indicators 22A-22J(collectively “22”) are displayed. The month indicator 24 is displayedin alignment with the scrubber 18. In the depicted embodiment, thevisible list portion 216 includes images 16 which were captured in May2010. Accordingly, the month field indicator 24 reads “May 2010”. Theyear field indicators 22A-22J indicate different years in which images16 where captured before and after the images 16 of the visible listportion 216. The order of the years in the year field indicators 22indicates that the list of images 16 is sorted such that the most recentimages 16 are at the top of the list 200, i.e. they are in a descendingchronological order. The month field indicator 24 is located between theyear field indicator 22B representing the year 2010, and the year fieldindicator 22C representing the year 2011.

The scrubber 18 may be dragged upwards, in an upward scrolling gesture,towards the year field indicator 2011 to increment the month displayedby the month field indicator to June 2010. Continuing to drag thescrubber 18 upwardly causes the month field indicator 24 to keepincrementing. When the scrubber 18 is in alignment with the year fieldindicator 22C corresponding to 2011, the month field indicator 24changes to “January 2011”. FIG. 4 depicts the user interface 14 after,starting from the position in FIG. 3, the scrubber 18 was dragged in anupward scrolling gesture until the month indicator read “Aug. 2012”.Within the month of August 2012, a first date indicator 20A reads “Sat.,Aug. 11, 2012”. Accordingly, the image 16A which is rendered under thefirst date indicator 20A was captured on that date. Similarly, a seconddate indicator 20B reads: “Sun. Aug. 5, 2012”, and the photos and videos16B rendered under the second date indicator 20B were taken on thatdate. The user interface 14 of the photo viewing application also showsa location indicator 25 next to the date indicator 20A. This indicatesthe location of the photo 16A taken on the date indicated by the dateindicator 20A.

In the depicted embodiment of FIGS. 2-4, as the scrubber 18 is draggedin either an upward or a downward scrolling gesture, the visible listportion 216 is updated in real-time. The contents of the visible listportion 216 are updated to reflect the current position of the scrubber18 in relation to the year field indicators 22. For example, as shown inFIG. 4, the scrubber 18 is positioned between the year field indicator22D corresponding to 2012 and year field indicator 22E corresponding to2013. The month field indicator 24 reads “August 2012”, and the images16 on the touchscreen display 45 are from days in August 2012.

In view of FIGS. 2-4, it can be seen that scrolling based on a singleattribute, the date, is possible with the known scrubber 18 interface.However, images 16 can have other attributes such as location and photocontent. Furthermore, the scrolling method shown in FIGS. 2-4 issequential in nature. For example, if it is desired to scroll from May2011 to June 2015, one has to scroll through every single month betweenMay 2011 and June 2015. If certain months have a high number of images16, then the scrolling will take longer.

In a list 200, each element 210 may have a plurality of attributes. Forexample, in a list of images representing photos or videos each imagemay have a date attribute, a location attribute and a content attribute.Attributes may be classified into a number of categories. A nominalattribute is used to name or label an element without any quantitativevalue. There is no intrinsic ordering to nominal data. Examples ofordinal attributes include age, gender, shape and color. Ordinalattributes categorize data with an order. Examples of ordinal attributeinclude time, distance and weight. An ordinal attribute may be comprisedof a plurality of fields. For example, a time attribute may be comprisedof a year, a month and a day; or an hour, a minute and a second. Adistance attribute may be comprised of kilometers, meters andcentimeters.

To manipulate or scroll through a list 200 of elements 210 taking intoaccount either the elements' 210 ordinal or nominal attributes, someuser interface elements are introduced. With reference to FIG. 5A, anexample ordinal attribute field control 70 is shown. In the depictedexample, the ordinal attribute field control 70 corresponds to a yearfield of a time attribute. The ordinal attribute field control 70 iscomprised of a top half portion 72A, a bottom half portion 72B and anattribute field value caption 74. A virtual line 71 separates the tophalf portion 72A and the bottom half portion 72B. The attribute fieldvalue caption 74 displays the current attribute field value of anelement associated with the ordinal attribute field control 70. Thecurrent attribute field value can be incremented by touching the tophalf portion 72A, and decremented by touching the bottom half portion72B. The attribute field value caption 74 is updated to reflect thecurrent attribute field value in real-time. For example, if the bottomhalf portion 72B is touched by a finger or a touch input tool, then theattribute field value “2001” which represents a year is decremented to“2000”. If the touch persists on the bottom half portion 72B the year isdecremented again from “2000” to “1999”. Conversely, the attribute fieldvalue is incremented when the top half portion 72A is touched. If boththe top half portion 72A and the bottom half portion 72B are touchedthen the attribute value remains the same. An ordinal attribute having aplurality of fields can be manipulated using a plurality of nominalattribute field controls 70 as will be described below. In someembodiments, the distance between the point of touch of top half portion72A or the bottom half portion 72B and the virtual line 71 determinesthe speed by which the attribute field value increments or decrements.For example, touching the top half portion 72A in proximity to thevirtual line 71 may increment the year by 1 year every second, buttouching the top half portion 72A at a farther distance from the virtualline 71 may increment the year by one every half a second. In anotherembodiment, the ordinal attribute field control 70 of FIG. 5A incrementsand decrements the corresponding attribute field value in response toswipes. For example, to increment the attribute field value a finger 30or a touch input tool is swiped upwardly such that it first touches thebottom half portion 72B, then touches the top half portion 72A.Conversely, to decrement the attribute value a finger 30 or a touchinput tool is swiped downwardly such that it first touches the top halfportion 72A and then touches the bottom half portion 72B.

FIG. 5B depicts an alternate embodiment of the ordinal attribute fieldcontrol 70 which features an increment arrow 76A for incrementing theattribute field value corresponding to the attribute field control 70and a decrement arrow 76B for decrementing the attribute field value.

FIG. 5C depicts another embodiment for an ordinal attribute fieldcontrol 70. In this embodiment, the attribute field control 70 respondsto actions on an active area located below it. For example, the activearea 75 is located under the attribute field control 70 of FIG. 5C. Toincrement the attribute field value associated with the attribute fieldcontrol 70, the user touches the active area 75 and swipes upwardlytowards the attribute field control 70. In response the attribute fieldcontrol 70 moves upwardly and the attribute value is incremented, inthis case to the year “2002”. The attribute field value caption 74 isupdated to read “2002”. Further swiping in the upward direction causesfurther incrementing of the attribute value to “2003” and the attributefield control 70 is also moved upwardly remaining just above the activearea 75. Conversely, when a finger or a touch input tool first touch theactive area 75 and is swiped downwardly, the attribute field control 70is also moved downwardly maintaining its position just above the activearea 75 and the attribute field value is decremented, in this case tothe year “2000”. The advantage of this control is that the attributefield value caption 74 is visible during incrementing and decrementingthe attribute value. In some embodiments, an upward swipe may decrementthe attribute field value and the downward swipe may increment theattribute field value.

In yet another example embodiment (not shown), the attribute fieldcontrol has a top active area above it and a bottom active area belowit. Touching the top active area increments the attribute value whiletouching the bottom active area decrements the attribute value.

A nominal attribute typically takes one of a plurality of attributevalues which are not quantitative. For example, a person may be one of:old, young and a baby. Accordingly, to select a nominal attribute value,a control which permits the selection of one value is appropriate. FIG.5D depicts an example nominal attribute radio button control group 80.The radio button control group 80 is comprised of three nominal radiobutton attribute field controls 81_1, 81_2 and 81_3 (collectively “81”).The radio button attribute field control 81_1 displays a caption 84_1containing a value of “Old”, the radio control attribute field button81_2 displays a caption 84_2 containing a value of “Young”, and theradio button attribute field control 81_3 displays a caption 84_3containing a value of “Baby”. In one embodiment, touching a radio buttonattribute field control 81 associated with an attribute, assigns thecorresponding attribute field value indicated by the caption 84 of thatradio control button attribute field control 81 to the correspondingattribute. For example, in FIG. 5D the radio button attribute fieldcontrol 81_3 was touched and became activated. Therefore the nominalattribute corresponding to the radio button control group 80 is assignedthe value “Baby” which is indicated by the caption 84_3. The radiobutton control 81_3 now also displays an activation indicator 82_3indicating that it is the active radio button attribute field control 81in the radio button control group 80. In another embodiment, theattribute value is assigned the value associated with a radio buttonattribute field control when a finger or touch input tools is releasedfrom the radio button attribute field control 81. For example, if theradio button control group 80 is rendered on the viewing area 102 of atouchscreen display 45, the user may swipe a finger 30 until it is onthe radio button attribute field control 81_3. Then upon lifting thefinger 30, the attribute value is assigned the value associated with theradio button attribute field control 81_3 (i.e. “Baby”).

While the attribute field controls 70 and 80 are depicted as being ovalin shape, it would be understood by those of skill in the art that othershapes are contemplated and would perform the same functions.Furthermore, other controls which permit incrementing and decrementing avalue are contemplated as ordinal attribute field controls.Additionally, other controls which permit selecting a value from among anumber of other preset values are contemplated as nominal attributefield controls.

An example embodiment of a user interface which facilitates scrolling alist of elements based on a plurality of attributes of is shown in FIG.6. An electronic device 10 having a touchscreen display 45 is depicted.The touchscreen display 45 has a viewing area 102 on which a userinterface 54 is rendered. The user interface 54 features a scrubber 18,an around scrubber area (ASA) 28, and an attribute selection view 60.The ASA 28, which is the area around the scrubber 18, is displayed onthe right side of the touchscreen display 45. The ASA 28 is shown as anelongate rectangular shape which has a top end 28A and a bottom end 28B.In the depicted embodiment, the attribute selection view 60 is displayedon the left side of the viewing area 102 of the touchscreen display 45.The attribute selection view 60 is comprised of a plurality of attributeselection elements 62A-62H (collectively “62”). Each attribute selectionelement 62 represents an attribute of an element 210 of a list 200. Inthe depicted embodiment, the attribute selection elements 62A-62Hrepresent attributes A1-A8, respectively. Each one of the attributesA1-A8 may be an ordinal attribute or a nominal attribute. The attributeselection elements 62 can each be used to select a correspondingattribute (A1-A8). A selected attribute is used to affect the scrollingor filtering of the list of elements 200 as will be described below. Aselection distance threshold (SDT) 32 is shown as a virtual verticalline parallel to the right edge 45A of the touchscreen display 45. TheSDT 32 defines a threshold for activating an attribute (A1-A8)corresponding to an attribute selection element 62. For example, in FIG.6 it is desired to activate the attribute A7. Initially the user touchesthe screen at the ASA 28 with the finger 30. At this point the user mayscroll the viewing area 102 using upward or downward scrolling gesturesusing the scrubber 18, as described earlier. However, in this case, itis desired to select and activate the attribute A7 to be used in thescrolling. The user swipes the finger 30 towards the activation point32G, in an attribute activation swipe. The activation point 32G is apoint on the SDT 32 which is in horizontal alignment with the attributeselection element 62G corresponding to attribute A7. A swipe indicator19D is displayed as the finger 30 is swiped diagonally, in the attributeactivation swipe, towards the SDT 32. The swipe indicator 19D is anoptional shape that assists the user in determining which attribute(A1-A8) will be activated if finger 30 continues to be swiped in thesame direction until it reaches a point on the SDT 32. The finger 30reaches the activation point 32G on the SDT 32. The activation point 32Gis aligned horizontally with the attribute selection element 62G, asrepresented by a horizontal line 36G. Accordingly, the attribute A7corresponding to the attribute selection element 62G is activated. Whenthe attribute A7 is activated, the corresponding attribute selectionelement 62G is highlighted as shown. FIG. 6 also shows the attributeselection element 62D as highlighted indicating that the correspondingattribute A4 was previously activated. Accordingly, multiple attributes,such as A1-A8 can be activated by using different attribute activationswipes on the screen from the ASA 28 towards a point on the SDT 32 inalignment with the desired attribute selection element 62. Onceattributes are activated, the corresponding attribute field controls(70, 80) are displayed to assist in scrolling or filtering based on theactive attributes, as will be described below.

In order to distinguish between an attribute activation swipe, such as19D, and the upward or downward scrolling gestures, the attributeactivation swipe is preferably at a significant angle θ with respect tothe vertical so it is distinguishable from a swipe which is parallel tothe scrolling direction. For example, when activating the attribute A8,it is preferable to initially swipe the finger 30 in a downwardscrolling gesture towards the bottom end 28B of the ASA 28, then swipeit diagonally towards the activation point 32G on the SDT 32. Similarly,if the attribute “A1” is to be activated, the finger 30 is preferablyswiped to the top end 28A of the ASA 28 then swiped diagonally to apoint on the SDT 32 which aligns horizontally with the attributeactivation element 62A corresponding to the attribute “A1”. The angle θis preferably 30 degrees or higher.

Once an attribute has been activated, as described above with referenceto FIG. 6, the corresponding attribute value can be changed to affectthe scrolling or filtering of a list 200 of elements 210. FIG. 7 depictsan example embodiment where the “Time” attribute has been activated bythe method described in FIG. 6, above. As such the finger 30 is showntouching the screen at the point of activation 32D which is in alignmentwith the attribute selection element 62D corresponding to the “Time”attribute. The “Time” attribute is an ordinal attribute comprised ofthree fields: a year, a month and a day. In response to the activationof the “Time” attribute, ordinal attribute field controls 70D_1, 70D_2and 70D_3 (collectively “70D”) corresponding to the “Time” attribute aredisplayed above the point of activation 32D. The attribute field control70D_1 represents the year, the attribute field control 70D_2 representsthe month, and the attribute field control 70D_3 represents the day.

At this point, with the attribute field controls 70D displayed,scrolling through a list of elements each having a time attribute can bedone by manipulating one or more attribute field controls 70D, asdescribed above with reference to FIGS. 5A-5C. For example, if theattribute field controls 70 shown in FIG. 7 are similar to the attributefield controls of FIG. 5A, the finger 30 may be swiped upwardly inrelation to the attribute field control 70D_1 thus incrementing theyear, until it reads “2005” for example. By incrementing an attributefield control such as 70D_1, the attribute field value (in this case the“year”) associated with the attribute field control 70D_1 isincremented. As a result, the attribute value for the “Time” attributeis also updated, in this case to 14 January, 2005. In response toupdating the attribute value for “Time”, the contents of the viewingarea 102 are scrolled so that the elements displayed are centered around14, January, 2005. Without lifting the finger 30 off the screen, thefinger 30 may be swiped to the left to manipulate the month attributefield. For example, the month attribute field control 70D_2 may bemanipulated to increment the month to “July”. This results in theattribute value for “Time” being changed to 14, July, 2005. In response,the contents of the viewing area 102 are scrolled so that the elementsdisplayed are centered around 14, July, 2005. Similarly, the finger 30may be swiped further to the left to manipulate the date attribute fieldcontrol 70D_3. Manipulating the attribute field controls 70D updates thevisible list portion 216 of a list of elements in this case by scrollingup and down a list 200. Specifically, the attribute field controls 70Dallow scrolling of a list 200 of elements 210 by different fields of anordinal attribute since changing the attribute field values associatedwith the attribute field controls 70D results in changing the attributevalue, which is comprised of the individual attribute field values. Asdiscussed, the “Time” attribute value is comprised of the year attributefield control value, the month attribute field control value and thedate attribute field control value. In this case, the differentattribute fields represent different levels of granularity. For example,manipulating the year attribute field control 70D_1 causes fastscrolling of the list 200 by the coarse granularity of a year.Manipulating the month attribute field control 70D_2 causes scrollingwith the finer granularity of a month. Accordingly, using the earlierexample discussed above where it was desired to scroll from May 2011 toJune 2015, the year attribute field control 70D_1 can be manipulated toincrement the year from 2011 to 2015, then the month attribute fieldcontrol 70D_2 can manipulated to increment the month from May to June.Advantageously, the content displayed on the viewing area 102 of thetouchscreen display 45 is scrolled efficiently to display the desiredvisible list portion 216 with a minimal number of swipe gestures.

In the aforementioned embodiment, shown in FIGS. 6-7, the scrubber 18 ishidden once an attribute is activated and the corresponding attributefield controls 70 are displayed. Once the attribute field controls 70are adjusted and the finger is lifted off the screen, the attributefield controls 70 are removed from the screen and the scrubber 18 isre-displayed. At this point the screen contents can be scrolled eitherusing touch flicks or using the scrubber 18. In some embodiments, if thescrubber 18 is not used for scrolling then after a brief period of timeit is removed. In other embodiments, the scrubber 18 is displayed evenduring the manipulation of the attribute field controls 70. Whenever thecontents of the viewing area 102 are scrolled, the position of thescrubber 18 is adjusted to indicate the position of the visible listportion 216 relative to the full list 200, as discussed earlier.

If it is desired to scroll through or filter the list 200 using a secondattribute, in addition to the activated first attribute, then a secondattribute is activated in the same manner described above using anactivation swipe towards the SDT 32. In response to the activation ofthe second attribute, the attribute field controls corresponding to thesecond attribute are displayed and can be used to scroll or filter thelist in conjunction with the first attribute. With reference to FIG. 8,an example embodiment is shown where a first “Time” attribute hasalready been activated and particular month and year have been selectedas described above. The attribute selection element 62D corresponding tothe “Time” attribute shows the currently selected month and year (as“June 2015”). A second “Faces” attribute is activated by swiping afinger 30 from the ASA 28 to a point 32B on the SDT 32 aligned with theattribute selection element 62B corresponding to the “Faces” attribute.The “Faces” attribute is a nominal attribute taking one of three values:“old”, “young” and “baby”. Accordingly, in response to activating the“Faces” attribute, a nominal attribute radio button control group 80,described above with reference to FIG. 5D, is displayed. The radiobutton control group 80 is comprised of three nominal attribute radiobutton controls 81_1, 81_2 and 81_3 corresponding to the nominalattribute values “old”, “young” and “baby”, respectively. The finger 30can be swiped onto any one of the radio button attribute field controls81_1 to select the corresponding attribute value. To complete theselection, the finger 30 is lifted off the screen. The attributeselection element 62B is highlighted and is updated to display anindication to reflect the attribute value selected. For example, if“old” is selected, then the attribute selection element 62B shows “Facesold” as shown in FIG. 8. Since the “Faces” attribute is a nominalattribute, it is used to filter the displayed elements of the list 200.Accordingly, when the “Faces” attribute is set to the value “old” thenonly photos of adults over 65 years old are displayed as part of thevisible list portion 216. As shown in FIG. 8, the “Time” attributerepresented by the attribute selection element 62D is also highlighted.Therefore, both the “Faces” and “Time” attribute are used to determine avisible list portion 216 of a list of elements, such as photos, to bedisplayed on the touchscreen display 45. In this example, the nominal“Faces” attribute filters the list, while the “Time” attribute permitsscrolling by year, month or day. The user can re-activate the Timeattribute by swiping from the ASA 28 towards the point 32D as before.Once the Time attribute has been reactivated, the attribute fieldcontrols 70D can be used to scroll up and down the visible list portion216 which is now also filtered to only show photos of adults over 65years old. In some embodiments, to clear a selected attribute, the usercan tap the corresponding attribute selection element. For example, toclear the “Faces” attribute, the user can tap the attribute selectionelement 62B. In other embodiments, a dedicated “Reset” control isdisplayed in the attribute selection view 60, similar to the attributeactivation element 35A of FIG. 10 discussed below.

Another example embodiment for activating attributes is depicted inFIGS. 9-15. In one example embodiment, an attribute activation view 34is originally hidden and is displayed in response to an attributeactivation view 34 activation action, such as an attribute activationview 34 activation swipe. With reference to FIG. 9A, an attributeactivation view 34 is displayed in response to an activation swipe inwhich the scrubber 18 is swiped to the left in the direction 19E, awayfrom the attribute activation view and towards the central region of theviewing area 102. Alternatively, as depicted in FIG. 9B, an attributeactivation view 34 is displayed in response to by swiping on the bezel45B to the left in the direction 19E.

FIG. 10 shows the attribute activation view 34 rendered as alongitudinal rectangular user interface element along the right edge 45Aof the touchscreen display 45. The attribute activation view 34 iscomprised of a plurality of attribute activation elements 35A-35H(collectively “35”). In this example embodiment, the first attributeactivation element 34A serves as a reset user interface element whichclears all active attributes associated with the attribute activationelements 35. An attribute is activated by touching the correspondingattribute activation element 35 with a finger 30 or touch input tool,and then swiping to the left towards the middle of the screen. Forexample, in FIG. 10, the “Time” attribute has been selected by touchingthe corresponding attribute activation element 35D and swiping to theleft in the direction 19E. In response to the activation of the “Time”attribute, the ordinal attribute field controls 70D_1, 70D_2 and 70D_3are displayed as discussed before. The finger 30 can then be furtherswiped in the direction 19E until it is aligned with the attribute fieldcontrol 70D_1 corresponding to the year field. The year can beincremented or decremented by swiping up or down under the yearattribute field control 70D_1 as described earlier with reference toFIG. 5C. In response to changing the year, the content of the viewingarea 102 of the touchscreen display 45 is updated accordingly. Asdiscussed above, the “Time” attribute is an ordinal attribute, andtherefore the attribute field controls 70D can each be used to scroll upand down a visible list portion 216, such as a list of photos asdiscussed above. For example, to scroll by a granularity of one year ata time, the finger or touch input tool is swiped up or down below theattribute field control 70D_1, as discussed above with reference to FIG.5C. To scroll through the list 200 by a granularity of a day, the finger30 is further swiped in the direction 19E until it is just under theattribute field control 70D_3 corresponding to the day. The attributefield control 70D_3 can then be used to increment or decrement the dayfield of the “Time” attribute. Accordingly, the contents of the viewingarea 102 of the touchscreen display 45 are scrolled by the granularityof a day.

The attribute activation view 34 may also contain nominal attributeswhich have a number of discrete values. FIG. 11 depicts activating anominal attribute, such as the “Faces” attribute. The “Faces” attributeis activated by first touching the corresponding attribute activationelement 35F, for example by a finger 30 then swiping to the left in thedirection 19E. The “Faces” attribute has 3 possible values: “old”,“young”, and “dog” represented by the nominal radio button attributefield controls 81F_1, 81F_2 and 81F_3 respectively. In response to theactivation of the “Faces” attribute, the nominal attribute radio buttoncontrol group 80 is displayed as described above with reference to FIG.8. To select the desired nominal attribute value, the finger 30 isfurther swiped in the direction 19E towards the middle of the viewingarea 102 until it is aligned with the corresponding radio buttonattribute field control 81. Then the finger 30 is swiped upwardly tomanipulate the radio button control 81 as discussed above. If it isdesired, for example, to restrict a list of images to the onescontaining “young” people, the finger 30 is swiped in the direction 19Euntil it is aligned with the nominal radio button attribute fieldcontrol 81F_2. Then the finger 30 is swiped upwardly until it is on topof the nominal radio button attribute field control 81F_2. When thefinger 30 is lifted off the nominal radio button attribute field control81F_2, the nominal attribute value corresponding to the nominalattribute “Faces” is set to “young”. Accordingly, also in response tolifting the finger 30 off the screen, the content being displayed on thetouchscreen display 45 is filtered such that only photos meeting thecriteria that they are of “young” people are displayed. As shown in FIG.12, the attribute activation element 35F has been updated to indicatethat the “Faces” attribute has been activated and set to the value“young”.

More than two attributes can be activated and assigned values to furtherfilter or scroll through the list 200. FIG. 12 shows the activation of athird attribute, which is “Location”, by touching the correspondingattribute activation element 35B and then swiping in the direction 19E.In response to the activation of the “Location” attribute, the attributefield button controls 81B_1, 81B_2 and 81B_3 are displayed. Theattribute field button control 81B_1 allows filtering a list of elementsby continent, the attribute field button control 81B_2 allows filteringthe list by country and the attribute field button control 81B_3 allowsfiltering by city. In an example embodiment, the values corresponding toeach button control are limited to values that apply to the list 200being displayed. For example, when the finger 30 is further swiped, inthe direction 19E, until it is aligned with the attribute field control81B_1 which corresponds to the continent, the finger 30 may be furtherswiped upwardly or downwardly to select a continent. However, if thelist 200 contains elements 210 having continent attributes correspondingto only “North America” and “Asia”, then other continent values are notshown in response to the upward and downward swipes. Furthermore, due tothe relationship between the continent, country and city, selecting oneattribute field value may affect other field values. For example, if thefinger 30 is swiped until it is aligned with the city radio buttoncontrol 81C_3, then swiped upwards. The city field control changes todisplay city names corresponding to elements 210 in the list 200. If thecity “Montreal” is selected and the finger 30 is lifted, then the cityattribute is set to “Montreal”. Furthermore, the country attribute isset to “Canada” and the continent is set to “North America”. As anotherexample, if it is desired to show any elements 210 of the list 200,which have a country field value of “Canada”, then the finger 30 isswiped in the direction 19E until it is aligned with the attribute fieldcontrol 81B_2 and then swiped up or down until the value “Canada” isselected. In this case, the continent is automatically set to “NorthAmerica” and the city is set to any city, i.e. it may just be left blankto match any city in Canada. Accordingly, if the list 200 comprises aplurality of images, only images taken in Canada are displayed. FIG. 13shows the location attribute represented by attribute activation element35B as being set to “Canada”.

If it is desired to clear an active attribute, the correspondingattribute activation element 35 is tapped. For example, as shown in FIG.13, the “Location” attribute, which is set to “Canada”, can be clearedby tapping the attribute activation element 35B by a finger 30. The“Location” attribute is cleared as shown in FIG. 14. The attributeactivation element 35B corresponding to “Location” simply indicates“Location” and no longer displays the selected location field value“Canada”. Additionally, the attribute activation element 35B is nothighlighted indicating that it is not taken into account in anyfiltering or scrolling. If it is desired to clear all the attributes,then tapping the attribute activation element 35A will activate a resetcommand that clears all settings for the attribute activation elements34B-34H. Alternatively, one can tap each active attribute activationelement 35 to deactivate it and clear all its settings.

With reference to the attribute activation elements: 35B, 35D and 35F,in FIG. 15A, the “Faces” attribute has been set to “young” as indicatedby the attribute activation element 35F, the “Time” attribute has beenset to “March 2018” as indicated by the attribute activation element35D, and the “Location” attribute has been set to “Canada” as indicatedby the attribute activation element 34B. Accordingly, a visible listportion 216 of a list of photos shown on the touchscreen display 45 islimited to photos of “young” people taken in “Canada” around March 2018.Further scrolling is possible using an active ordinal attribute. Forexample, in the shown figure, finger 30 is placed in alignment with theattribute activation element 35D which is already activated and shown asbeing highlighted. The finger 30 can be swiped to the left in thedirection 19E to select a time attribute field control for use inscrolling. For example, the finger 30 can be swiped to the left until itis in alignment with and just below the attribute field control 70D_1,as shown in FIG. 15B. Then the finger 30 can be swiped up or down toincrement or decrement the year attribute field value. In a descendinglist, an upward scrolling gesture under the attribute field control70D_1 will increment the “Time” attribute by a single year at a time.For example, the “Time” attribute will be incremented to “March 2019”,then to “March 2020”. Accordingly, the visible list portion 216 of thelist of photos is scrolled accordingly and displays photos of “young”people taken in “Canada” around March 2019 and then around March 2020,respectively. In another example, the finger 30 is further swiped to theleft, in the direction 19E, until it is in alignment with the attributefield control 70D_2, which represents the month field of the “Time”attribute. Further swiping the finger 30 in an upward scrolling gesture,will increment the “Time” attribute by a single month. The “Time”attribute in that case will have a value of 14 Apr. 2018. The list 200which may be comprises of images, is scrolled to show pictures of youngpeople in Canada taken around 14 Apr. 2018.

In some example embodiments, when no interactions with the attributeactivation view 34 takes place for a predetermined period of time, thenthe attribute activation view 34 disappears from the viewing area 102 ofthe touchscreen display 45, as shown in FIG. 16. Similarly, in someembodiments, when no interactions with the scrubber 18 take place for apredetermined period of time, the scrubber 18 is removed from thetouchscreen display 45, as shown in FIG. 17.

While touching an attribute activation element 35, and swiping in thedirection 19E towards the middle of the screen has been shown as amethod for activating a particular attribute, other alternative methodsare contemplated. With reference to FIGS. 18-20, there is presented amethod for selecting an attribute of an element 210 of a list 200, theattribute used to affect either scrolling or filtering the list 200. Inthe presented method, an attribute having an attribute activationelement 35 in alignment with the scrubber 18 is considered the activeattribute. The attribute activation view 34 is scrollable using touchflicks. For example, with reference to FIG. 18, if it is desired toactivate the attribute “A5” instead of the “Time” attribute, then theuser touch flicks the attribute activation view 34 in the direction 39as shown. The attribute activation elements 35B-35H scroll upwards byone position, as shown in FIG. 19. In this embodiment, the attributeactivation element 35A is static since it is the element which resetsthe values of all attributes and is activated by a single tap.Accordingly, as shown in FIG. 19, the attribute “A5” is aligned with thescrubber 18 and is therefore the currently selected attribute. In FIG.20, the scrubber 18 is touched while the “Time” attribute was alignedtherewith as shown in FIG. 18. In response to touching the scrubber 18,the attribute view 34 is hidden from the viewing area 102 of thetouchscreen display 45. The scrubber 18 is then displayed close to theedge 45A of the touchscreen display 45 as shown. The attribute fieldcontrols 70D can be manipulated as before, by swiping the finger 30 tothe left until it is aligned with and just below any one of theattribute field controls 70D. The finger 30 can then be swiped up ordown to increment or decrement the attribute value associated with theattribute field control 70D as described earlier.

In the example embodiments presented, the attribute selection and/oractivation views have had a longitudinal configuration and have beendisplayed near one edge of the touchscreen display 45. Other exampleembodiments, shown with reference to FIGS. 21-25, use a semi-ovalattribute activation view 218. With reference to FIG. 21, an electronicdevice having a touchscreen display 45 including a viewing area 102 isshown. A scrubber 18 is displayed proximate the right edge 45A of thetouchscreen display 45. The scrubber 18 is shown being touched by afinger 30. In response to receiving the touch, the scrubber 18 isexpanded into an attribute activation view 218, as shown in FIG. 22. Inthis embodiment the attribute activation view 218 is semi-circular inshape. The attribute activation view 218 includes attribute activationelements 220A, 220B and 220C corresponding to a location, time andperson attribute, respectively. FIG. 22 also shows the directions inwhich the finger 30 can be swiped to select and activate a particularattribute. For example, swiping the finger 30 in the direction of arrow219A until it is touching the attribute activation element 220A causesthe corresponding attribute, location, to be activated. Similarly,swiping the finger 30 in the direction of arrow 219B until it istouching the attribute activation element 220B, activates thecorresponding attribute, time. Swiping the finger 30, in the directionof arrow 219C until it is touching the attribute activation element 220Cactivates the person attribute.

In response to activating one of the attributes, the attributeactivation view 218 is reduced to show only the attribute activationelement 220 of the activated attribute. For example, with reference toFIG. 23, the attribute activation view 218 only shows the attributeactivation element 220B which corresponds to the time attribute.Additionally, the ordinal attribute field controls 70D_1, 70D_2, and70D_3 (collectively “70D”) corresponding to the year, month and date aredisplayed. At this point the finger 30 may be further swiped to the leftto be aligned with an attribute field control 70D, and then swiped up ordown to adjust the value of the attribute field control 70D as describedearlier. For example, with reference to FIG. 24, the finger 30 isaligned with the attribute field control 70D_2 and may be used tomanipulate the month, as discussed above. Similarly, as shown in FIG.25, the finger 30 may be further swiped to the left until it is alignedwith the attribute field control 70D_3 and may be used to manipulate thedate, as discussed above. After a period of scrolling inactivity, theattribute view returns to being a scrubber as displayed in FIG. 21.

The use of the method and user interface elements for scrolling andfiltering a list of items is not limited to touch screen displays onelectronic devices, and can be used with virtual reality and augmentedreality systems. For example, with reference to FIG. 26, an augmentedreality system 500 is shown. A person 400 is using an augmented realitydisplay 550 and wishes to filter or scroll through a list of elements200 as describe above. In an example embodiment the system responds toan air gesture by the user's hand 530. For example, the user may pinchthe hand 530 and moves it to grab a virtually displayed scrubber 18. Inresponse, the scrubber expands to an attribute activation view 218 asshown in FIG. 27. The user may swipe the hand 530 in mid-air, whilestill in a pinch configuration, in any one of the directions 219 towardsa corresponding attribute activation element 220 to activate acorresponding attribute. The hand 530 may then me moved towards the leftto be aligned with an attribute activation field and used to adjust thevalue of that field as described above but using mid-air hand gesturesinstead of swipes.

FIGS. 30 and 31 depict a method 3000, executed by an electronic device10. The method 3000 is for scrolling or filtering a list of elements ina viewing area 102 of a touchscreen display 45 of the electronic device10. The method starts at step 3010. At step 3020, a first activationinput for a first attribute corresponding to any element of a list ofelements is received. The activation input may be swiping to an SDT 32,swiping to an attribute activation element 35, or touching an attributeactivation element 35. In response to receiving the first activationinput, at step 3030 the electronic device 10 executes instructions whichcause displaying a first plurality of attribute field controls, such asattribute field controls 70 or 81. At step 3040, at least one of theattribute field controls (70, 81) receives a manipulation action. Themanipulation action may be touching part of an attribute field controls70 to increment or decrement a field value associated with an ordinalattribute. The manipulation action may also be touching a radio buttonattribute field control 81 to select one of a plurality of valuesassociated with a nominal attribute. At step 3050, in response to themanipulation action, the respective value of the first attribute ischanged. At 3060, the list 200 is scrolled or filtered in the viewingarea 102 of the touchscreen display 45 based on the first changed valueof the first attribute. At step 3070, the electronic device executesinstructions which check if a second activation for a second attributeof any element 210 of the plurality of elements 200 has been received.If no, the method ends at 3080 and is restarted whenever a firstactivation input is received per step 3020. If a second activation isreceived, control goes to step 3110 of FIG. 31. At step 3110, a secondplurality of attribute field controls, such as attribute field controls70 or 81 are displayed in response to receiving the second activationinput. At step 3120, at least one of the attribute field controls (70,81) receives a second manipulation action. At step 3130, in response tothe second manipulation action, a second value associated with thesecond attribute is changed. At step 3140, the list 200 is scrolled orfiltered in the viewing area 102 of the touchscreen display 45 based onthe second changed value of the second attribute.
